Final answer:
ADH aids in the control of blood volume by increasing water reabsorption in the kidneys.
Step-by-step explanation:
Antidiuretic hormone (ADH), also known as vasopressin, plays a crucial role in the control of blood volume by aiding in water reabsorption. ADH is produced in the hypothalamus and released by the posterior pituitary gland, then travels in the bloodstream to the kidneys. This process not only decreases urine volume but also helps restore blood volume and pressure. ADH (antidiuretic hormone) aids in the control of blood volume by increasing water reabsorption in the kidneys. ADH, also known as vasopressin, is produced by the hypothalamus and acts on the kidneys. It makes the collecting ducts in the kidneys permeable to water, allowing water molecules to be reabsorbed back into the blood through osmosis. This helps the body conserve water and regulate blood volume.
Therefore, option a) By increasing water reabsorption in the kidneys, is the correct answer.
